>By matching the combination of slides, any color can be exactly described.
You were supposed to throw that set out 6 months after you got it because the film fades - P
We used to get people giving us color numbers out of five year old Pantone books and then complaining the colors didn't match....well...duh ...
My new headache is glass, since I fix windows now...
Most people think the windows in their houses are clear, but unless they bought the cheapest piece of garbage windows made, they are not in fact clear.
They have a coating to reflect heat, and that coating has a color, and that color depends on who made the window, and cheap vinyl windows have no manufacturer names, because they are made in big extrusion plants and sold to whoever feels like being a Vinyl Replacement Window Company this week.
So...over and over I have to explain color matching...
And the coating is an emissive coating, so it also has metamer properties, it looks different outside than it does in the shop....
If you have ever wondered why you can't get a window fixed for $20 anymore, that's the reason why - P
>No two humans perceive anything exactly the same
I used to have a great demonstration piece, it had 2 pieces of plastic on it, colored the same, but one was a luminescent dye, the other wasn't. They were matched to appear identical under flourescent lighting. I used to show it to people inside, then step outside into the sunlight, where one piece would still appear orange, but the other would turn purple. I hsaw people step inside and outside the door 6 times looking at the thing because they couldn't believe what they were seeing.....
